Requirements for the host interface
The host interface of the CLX can be operated as an RS 422/485 or an RS 232 interface.
shows the recommended maximum cable lengths as a function of the selected
data transfer rate.

To prevent interference, do not lay the cables parallel with power supply and motor ca-
bles over long distances, e. g. in cable ducts.
5.4.2
Supply voltage
The CLX requires a supply voltage of 18 to 30 V DC for operation without a heater and
24 V DC +20 %/–10 % for operation with a heater (functional extra-low voltage in accor-
dance with IEC 364-4-41). The functional extra-low voltage can be generated by using a
safety transformer pursuant to IEC 742.
The power consumption of the individual types is as follows:

Power-up delay
The selected device number (default: 1) affects the power-up delay of the device. This is
useful if a large number of CLX (e. g. in the SICK network) are to be supplied from one power
source.
